Quick preface, we have the Aztech DSL5028EN modem for home use under BayanDSL. I've been having trouble playing online games when my family is using the internet connection to browse. I searched the web for tips on how to fix this and I learned about QoS.

However, the QoS settings for the Aztech DSL5028EN is really complicated and I can't find help anywhere online. Here's the image of the QoS page of the router:

Can anyone help me? I have no idea what to put into these fields. Thank you very muc!

The important thing really is to have your game traffic set to a higher priority than normal web (port 80) and bulk traffic (ftp:21, bittorrent:6881-6889, etc).

If you know what port your games run on it's easier. Quake 3 Arena for instance runs at port 27950, so you go to your router and set port 27950 to highest priority.

If you're not sure, another way is to set web and bulk traffic to lower than normal, that way they get set lower than your games (which will run on normal, as is the default) even if you don't set a custom rule. But this is potentially bad if your router only offers highest/higher/normal/low, because http traffic will get the same priority as ftp and other bulk, making your browsing less responsive. If you have normal/low/lowest, then set 80 to low, and your ftp and bittorrent ports to lowest.
